New Zealand Institute of Highway Technology - NZIHT

Overview

Reliable and cost-effective structural pavement design requires an in-depth understanding of many types of materials and road condition data. A modern pavement design practitioner should not only be able to document and interpret this information, but also synthesize data to derive reliable design assumptions.

This course focuses on the holistic analysis, synthesis and documentation of key types of pavement material tests as well as pavement condition data. The course places an emphasis on the way information is synthesized to facilitate rational decision making related to structural pavement design. The course includes computer work in which participants will implement the principles through use of the Rubicon software.

This course augments but does not replace the Pavement and Rehabilitation Design short course which focuses on pavement design procedures in accordance with Austroads and the TNZ Supplement, as well as the use of CIRCLY.

Length

1.5 day course.

Facilitator

Dr Fritz Jooste

Cost

$750 + GST per person
(minimum number apply before a course is confirmed)

Topics include

• Overview of the fundamentals of modern pavement analysis and design
• Pavement materials tests and their use
• Pavement condition data types and their use
• Basic principles of Falling Weight Deflectometer (FWD) data analysis
• Backcalculation of layer stiffnesses using FWD data
• Synthesizing pavement condition data to identify uniform subsections and formulate design assumptions
• Effective documentation and presentation of pavement condition data

On completion of this course participants will

•  Interpret most available types of materials and pavement condition data
• Analyze Falling Weight Deflectometer data to support pavement design decisions
• Combine and synthesize different materials and pavement condition data types to identify uniform subsections and derive design assumptions
• Effectively document and present project level pavement condition data

Who should attend

Persons who will benefit from this course are those who have had some exposure to pavement design but would like to acquire the tools and understanding to perform more in-depth and advanced analysis of road condition data to better utilize and document pavement condition data in support of design.
